Speeiiicationforming part of Letters Patent No. 32,372, dated May 2l, 1861.

To all whom, it may concern:

'Be it known that we, JOHN JONES, of the city, county, and State of New York, and A. K. RIDER, of Poultney, in the county of Rutland and State of Vermont, have invented a newand Improved Rotary Pump;` and we do hereby declare that the' following is a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, making apart of this specification, in whichw Figure'l is an elevation of the rear end of the improved pump, a portion of the shell of which is removed, showing the interior of the pump. Fig. 2 is asection through the casing of the pump, taken in the 4vertical plane indicated by red line x of Fig. l. Fig. 3 `is a diametrical section through Fig. 2, as indicated by the red line y y marked thereon.

Similar letters of reference indicate corresponding parts in the three gures.

This invention is a rotary force-pump wherein a continued rotary motion of two cogged disks inclosed within a tight casing of a circular shape is employed to produce the suc` tion and also the forcing-power of the pump,

said toothed disks being so arranged within the pump-casin g that rotary motion imparted to one disk will rotate the other, and that as the disks are rotated water will he drawn into the casing on one side thereof and lforced out through the eduction-pipe at the opposite side of this casing in a continued stream, all as will be hereinafter fully explained.

To enable those skilled in the art to make and use our invention, we will proceed to describe its construction and operation.

A A' represent. the two circular sides of the' pump-casing, which have holes through their centers for receiving the pump-shafts and annular grooves formed in their inside surfaces for receiving the packing a a.

B B represent a circular band, which may be cast in two semicircular parts, one part of which may be cast with the base portion C, which forms the stand or base of the pump.

The band B l5 is somewhat wider at its bottom than it is at the top, as shown in Figs. l and 2, and it has two elevations 'b b cast on its inside, which are nearly diametrically opposite to each other, the inside surfaces of which are concave, as will be hereinafter explained.

In the drawings, Fig. 2 shows the elevations b h cast with the semicircular half B of the band. Thistigure also shows the length of these elevations, their respective widths being represented in Figs. l and 2.

E is the induction-pipe, and F is the `eduction-pipe, which are diametrically opposite each other. The two circular sides A A are bolted tghtlv to the sides of the band B B', as shown in Figs. l and 3 of the drawings, and these parts form the casing of thepump, which is tightly packed at all its joints. One side A of this casing is in a plane perpendicular to the base, but the side A is inclined l more orless from the top to the bottom of the casing. 4

W'ithin `the casing` above described are two circular disks having teeth or cogs on their inside surfaces or those surfaces which Aare opposite each other. The backs or outside surfaces of said disks are flat and ground smooth, so that they will work tightly against packing a a and not allow Water to escape between them and the inside surfaces of the sides A A of the casing. The disks have shafts G G', one of which G has its bearings in the side A a-nd passes through this side A and receives a crank ll. The other shaft G has its bearings in the side A of the casing and is perpendicular to this inclined side. Thus the point where two lines would intel'- sect drawn through the axes of shafts G G would forni an obtuse angle. The inside surfaces of the rotaryT disks are made up of cogs or teeth J J J J, which on one disk radiate from a central convexity d, (shown in Figs. 2 and 3,) and on the opposite disk they radiate from a corresponding central concavity. (Shown in Fig. 3.) These teeth J are of the same size and shape on each disk, and the three surfaces or sides ofeach tooth are beveled or tapered inward from the circumference to the center of each disk, as shown in Figs. l, 2, and 3 of the drawings; but the surfaces lettered c e c care beveledontward from the center to the circumference of each disk. The teeth are thus tapering, or, if severed from the disks, of a pyramidal shape.V

There should be the same number of teeth on one disk as is on the other, and the teeth of one disk pass into the spaces between the teeth of the other disk, as shown in Fig. l. Thus the two disks are geared together when they are introduced within the casing of the pump, and by turning the shaft G its disk will give motion to the opposite disk, and both disks will be rotated by motion applied to one Of the shafts. As the back surfaces of the toothed disks, which bear against the sides A A of the casing, are in the same planes, it will be seen that the teeth J J J Jot` one disk will form large spaces between the teeth J J J J Of the Opposite disk at the bottom of the casing, which spaces will gradually diminish in capacity as they approach the top or narrow part of the casing, and as the teeth alternately pass this part of the casing the spaces will be completely filled up by the teeth from the center to the circumference of the disk, as shown in Figs l and 3.

It should be understood that the contact of One tooth with the other is from the center to the circumference of the teeth, and that these points of contact are constantly changing as their disks are rotated. At. the same time the sides of the teeth work together sufliciently tight to form good joints.

The periphery of each disk, with its teeth, is convex, and works tightly against the surfacesof the divisions b b', so that water will notbe permitted to pass back from chamber K to chamber L during the operation of lthe pump or when the disks are rotating in the direction indicated by the arrows in Figs. l and 2 of the drawings. These two chambers K and L are concentric with the axis of the casing, and their division-segments l) b' are arranged nearly Opposite each other, so that the upper division b will extend across the narrowest part of the casing and the lower division b across the widest part of the casing.

The Operation of the pump is as follows: Motion is communicated to the shaft G in the direction indicated by the arrows in Figs. l and 2, and the disk with its teeth on this shaft G will rotate in a vertical plane. This rotary motion of the driver will give motion tO the follower, which isinclined, as before described.

The air is now exhausted from chamber L and water rushes in to till its place. This water lls up the spaces between the cogs of the two rotating disks and isfrapidly carried over the lower division?) into the chamber K, from which it is discharged through eductiOn-pipe F in consequence of the lling up of the'waterspaces between the cogs as they approach and pass the narrow division b at the top of the casing. After the cogs pass this upper division b they commence to separate again, and

continue to separate and increase the spaces if betwen them until they pass the lower division b, and in this way the water is drawn into chamber L, carried from this chamber inte chamber K, and forced out through pipe F. The machine is therefore both a sticking and forcing one, and however rapidly the cogged disks may be rotated it will be seen that the water cannot be carried around them or past the narrow division b at .the upper part of the casing, for the cogs at this point will entirely iill up the water-spaces, and wat-er cannot pass through the center of the disks from chamber K to chamber L, for the ball-andsocket joint CZ will completely prevent it.. Therefore all the water which is carried by the large spaces from chamber L to chamber K will be forced through pipe F in consequence of the gradual coming together of the cogs as they pass toward the division h.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The two rotary disks constructed with radial and tapering` cogs engaging with each other, as herein described and shown, and arranged in different planes within a tight casing, which is separated into two concentric chambers by divisions b b', substantially as and for the purposes herein set forth.
